I don't know anything about GOOGLE FROOGLE FEEDER (I think it's US only, isn't it?) and it's product_type handling. But quick updates does not add any input fields because quick updates is designed to update existing fields only, not add new fields.

If you need a new field you need to add it to your database, and if you want to update that new field using quick updates 2.x you would need to update the code for it as well.

And if GOOGLE FROOGLE FEEDER is a contribution I think you should ask about this issue in the support thread of that contribution (or start one yourself).
